User:Dulcan/Alvin hints and questions
This page is a running review of what I found out on the XO laptop beginning December 21, 2007. I purchased the laptop with 20 friends at work in the 2 for 1 deal. The information was obtained through trying it out and various help pages on http://laptop.org and http://wiki.laptop.org. Feel free to contribute to help us laearn more about using the laptop. This document was started with vi in the Terminal Activity and copied to the Write Activity using the Browser Activity to see the file system. It was, in turn, copied to this page. Liberal use was made of ctrl-a to select all, ctrl-c to copy, and ctrl-v to paste. All of the editing was performed with the XO laptop.See also at the bottom of the page has useful links.
Questions/Problems
- Collaboration: How tp I get together with other laptop owners in Fremont, Palo Alto, or Mountain View, California? I expect a lot of people from Google bought it, so I can probably go there.
- How to switch the screen between color to black and white
- Where do the activities actually store the files.
- When will we geet a print capbility, maybe lpr.
- Sometimes the touchpad goes haywire; reboot fixes; maybe a memory management problem
- Wireless does not support wpa encryption. wep works. I used shared key with HEX. I needed a reboot to make it work.
- How to listen to an mp3 file:
- If downloaded from the web, a Journal entry is created, but it only seems to let you do it once in Etoys. It fails the second time.
- Why is my touchpad jumpy or ue a USB mouse.
- a*if it is on a USB drive, use the Journal to launch it. It launhes in Etoys. It plays one file at a time.
- Spreadsheet: This killer app is not ready yet. It is listd on the download page as in development. Google online spreadsheet can be used
Journal Activity
- This should be the focus for running the activities
- It is best to resume a journal entry to reduce the numbr of entries.
- Clean up is slow because you can only delete journal entries one at a time.
- What does the * mean in the journal? In gmail, a star can be selected as an object for an action.
